Stabbing pains in bum

Kathy

Hi everyone! I’m a bit confused! I’m 37 weeks pregnant and baby is still moving about and kicking etc, but today when she moves I get a really strange stabbing pain in my vagina and my bum, is this normal?? I never had this sensation with my first little one and it’s quite painful 😖 I have a hospital appointment tomorrow afternoon but just wondering if anyone else has had this happen?

TIA

Kathy
